Beschreibung
Zusammenfassung:	A charge device (200) converting electric power from an external power supply (260) into a charging electric power for a power storage device (110) is configured to allow power conversion bidirectionally. An AC/DC converter (210) of an external charging system converts AC power of a power line (ALC1, ALC2) into a charging electric power for an auxiliary battery (180). A DC/DC converter (170) of the vehicle running system converts the electric power from the power storage device (110) into the charging power for the auxiliary battery (180). When charging of the auxiliary battery is requested, a control device (300) selectively executes a first charge of converting the electric power of the power storage device (110) by the DC/DC converter (170) to charge the auxiliary battery (180), and a second charge of converting the electric power of the power storage device (110) by a charge device (200) and the AC/DC converter (210) to charge the auxiliary battery (180), according to an output state of the auxiliary battery.
